Sydney Development Corporation (SDC) was the first publicly traded software company in Canada. Founded by Tarrnie Williams, SDC developed an online real-time project management system for the IBM System/370^{[citation needed]} mainframe computer, then various different business applications for microcomputers such as the Apple II, and eventually became the first developer and publisher of computer games for microcomputers in Canada.^[1][2]

In 1981, SDC agreed to publish Evolution by Don Mattrick and Jeff Sembers, after Williams's 10-year-old son enjoyed a demo of the game.^[3] Evolution sold over 400,000 copies, and Mattrick and Sembers went on to found Distinctive Software.^[4]
